'The free end portion of the rubber covering housed `bythe fabricsheathing '.13 ispushed inwardly, Figure 2B, to expose the conductivewires of the core 16 and such free1 end portion fastenedY to theunderneathpart of 1 thecore. The exposed conductive wires of the core16,.are rthen separated into at least two strands or strands The'wiresof the outer layY 21 of the second portion'20," Figure 3, are foldedback from the free end thereofin multiplies 21a, in this instancemultiples of 9 each, and for a predetermined length, in this instance `3feet from the free end. of the portion 20. Next, the

wires of the inner lay 22 of' the second portion V20,

Figure 3A, are folded back from the free end thereof in multiples22a,'in this instance, multiples of 3 each, and for Ia length less thanthat of the outer l-ay 21 of the portion 20, .in this instance 1 foo/tfrom the free end of the portion 2i). yWith the folding back of thewires in multiples 22a of the inner lay 22 of the portion 2 0 thisuncovers adjacent portion of the core of the cable and housed by therubber covering and the fabric sheathing encasing such covering andgenerally indicated by thenumenal 23. Next, the free end portion of therubber covering housed by the fabric sheathing is pushed inwardly,Figure 3B, to expose the conductive wires of the core 26 and .such freeend portion fastened to the underneath part of the core.

The exposed vconductive wires of the core 26 are then separated into atieast two strands or strands 25.

Thestrands 25 lof the separated core part of the second portion 20 andthe strands 15 of the separated core part of the first portion 10 anetwisted about each other to form '1an interconnected section generallyindicated by .the numerd 3i), Figure 4, connecting the cores 26/and 16of the portions 2) and 10 together. The interconnected section is thenintegrally connected tothe rubber casings. This is doneby wrapping abinding tape 31 about the interconnected sectiont. Upon completion ofthe wrapping tof the binding tape about the section 30 the two free endportions o-f the lrubber casing-sheathings 23 and 13 are released andshifted so that the 4free ends are adjacent -to and spaced from eachother, -Figure 5. The portion of the fabric sheathings adjacent the freeends of the rubber casings are removed, whereupon theft-ee ends of therubber casings are vulcanized to form la onepiece rubber casing aboutthe connected-section 30. An insuiating tape 32, Figure 6, is thenwrapped labout the rubber casingcorresponding to the interconnectedsection 3 0.

Upon completion of the Wrapping of the insulating tape 32 about therubber casing corresponding to the interconnected section 30, the foldedback wire multiples .12a of the inner lay 12 of the rst portion lil,Figure 7,'` are successively'wrapped about theinsulating tape 32 on theinterconnected section 30 up to the folded back wire multiples 22a ofthe innerrlay 22 of the second portion 20 and lock the respectivewrappings together about the section 30. At this point the two foldedback wire multiples 21a of the outer lay 21 are folded back topractically the remaining eighteen feet or to the point adjacent theterminating point'or Yother end of the' 22 foot rst Vportiontlior asindicated y in dotted lines in Figure 7, whereupon one of the multiples22a of the inner lay 22 of the second portion 20 is unlocked from theadjacent one of the multiples 12a of the inner lay 12 of the rst iportion and is unwrappeduntil it is adjacent to and spaced apredetermined length from the folded back mul- I tiples 21a of the outerlay 21 of the second portion 20, or in this instance a length of 3 feetand indicated by the letter A in Figure 7A. Next, the adjacent one ofthe t multiples 12a of the inner lay 12 of the rst portion 10 is Wrappedin the space vacated by the unwrapped one multiple 22a of the secondportion 20 until the free end portion engages the unwrapped one multiple22a of the inner lay 22 of the second portion 20 and lock the Wrapped fmultiple to the unwrapped multiple. Upon conclusion of the locking ofthe wrapped multiple with the unwrapped multiple, a second of the tiveremaining multiples 22a of the inner lay 22 of the second portion 20 isunlocked from the adjacent one of the multiples 12a of the inner lay 12of the rst portion 10 and is unwrapped until it is adjacent to andspaced a predetermined length from the locked one wrapped multiple tothe unwrapped multiple indicated by the letter A or in this instance,the same length or 3 feet, and indicated by the letter B in Figure 7A,whereupon the adjacent second one of the multiples 12a of the inner lay12 of the iirst portion 10 is wrapped in the space vacated by theunwrapped second one of the multiples 22a of the second portion 20 untilthe free end portion engages the unwrapped second one of the multiples22a of the inner lay 22 of the second portion 20, and lock the wrappedmultiple to the unwrapped multiple. This unwraping of each of theremaining four multiples 22a of the inner lay 22 of the second portion20 followed by the wrapping of the adjacent one of the multiples 12a ofthe inner lay 12 of the first portion 10 vacated by the unwrappedmultiple with the free end portion of the wrapped multiple engaged andlocked to the K unwrapped multiple is performed in turn, but with themultiple 22a of the inner lay 22 of the second portion 26, letter A ofFigure 7A, and said one wire is unwrapped until it is adjacent to andspaced a multiple of the length of the spacing of the engaged said onewrapped and nn- Wrapped multiples 12a and 22a from the folded backlmultiples 21a of the outer lay 2l of the second portion 2i), suchmultiple in this instance being one foot as shown in Figure 3B,whereupon one of the wires is separated from the engaged wrapped Saidone multiple 12a of the inner lay 12 of the first portion 1@ and wrappedin the space vacated by the unwrapped one wire of said `one multiple 22aof the portion 20 until the free end portion engages the unwrapped onewire of the multiple 22a of the portion 2t) and lock the wrapped wire tothe unwrapped wire. Following this, another one of the wires isseparated from the engaged unwrapped said one multiple 22a of the innerlay 22 of the second portion 2t?, letter A of Figure 7A,

and said another wire is unwrapped until it is adjacent to j and spaceda multiple of the length of the spacing of the engaged said one wrappedand unwrapped multiples 12a and 22a from the folded back multiples 21aof the outer lay 21 of the second portion 2t) corresponding to the Ysame length multiple as that of said engaged one wrapped and unwrappedwires of the pair of multiples 12a and 22a of the portions 10 and 20,the latter multiple being in this instance one foot, whereupon anotherone of the wires is separated from the engaged wrapped said one multiple12a of the inner lay 12 of the rst portion 10 andwrapped inthespace'vacated by the unwrapped another wire of said one multiple 22a ofthe portion 20 until the free end portion engages the unwrapped anotherWire of the multiple 22a of the portion 20 and lock the wrapped anotherwire to the unwrapped another wire. This leaves the further andremaining one of the wires of the one multiple 22a of the inner lay 22of the second portion l20, at the position indicated by the letter A inFigure 7B engaged by the further and remaining one of the wires of theone multiple 12a of the inner lay 12 of the iirst portion 10. The abovedescribedprocedure as to the separation and unwrapping of the wires ofone of the multiples 22aiof the second portion 20 and separation andwrapping of the wires of one of the multiples 12a of the rst portion 10is repeated in turn with each of the remaining five multiples 22a of thesecond portion 20 and the complemental multiples 12a ofthe ytirstportion 10 until they are all in complementalgroups, Figure 7B showinggraphically that most of the pairs of wires are in assembled conditionwith several in process of assembled condition. At this point the excesswires of each pair is removed, and each pair in turn subjected to awelding operation which welds the wrapped wire to the adjacent wires,as. graphically depicted in Figure 8. Figure 7C illustrates theassembled inner lay of the spliced cable, the number 28 indicating therespective welds in the inner lay.

Upon completion of the formation of the assembled inner lay of thespliced cable the two folded back multiples 21a of 9 wires each of theouter lay 21 of the sec ond portion 10 are wrapped about such assembledinner lay until the free end portions are adjacent the folded backmultiples 11a of the outer lay 11 of the iirst portion 10,` the -freeend portions of each of the two folded back multiples 21a being thensubdivided into three multiples with each multiple having three wires.This results in the free end portions of the two multiples 21a beingsubdividedinto six multiples, with each multiple having three wires, asillustrated in Figure 9. Each free end portion of the six multiples 21ais engaged by the free end portion of one of the multiples 11a and lockthe two multiples together. Next, one of the multiples 21a of the outerlay 21 of the second portion 20 is unlocked from the adjacent one of themultiples 11a of the outer lay 11 of the iirst portion 10 and isunwrapped until it is adjacent to and spaced a predetermined length fromthe terminating end indicated by the numeral 29, Figure 9, of the secondportion 20 or in this instance a length of 3 feet from the end 29,whereupon the adjacent and unlocked one of the multiples 11a is wrappedin `the space vacated by the unwrapped one multiple 21a until the freeend portion engages the unwrapped one multiple 21a and lock the wrappedmultiple to the unwrapped multiple. Upon conclusion of the locking ofthe wrapped multiple with the unwrapped multiple, a second of the iiveremaining multiples 21a is unlocked from the adjacent one of themultiples 11a and is unwrapped until it is adjacent to and spaced apredetermined length from the locked one wrapped multiple to therunwrapped multiple or in this instance 'the same length as the firstone ylocked wrapped and unwrapped multiple from the end 29 or 3 feet,whereupon the adjacent second one of the multiples 11a of the iirstportion 10 is wrapped in the space vacated by the unwrapped second oneof the multiples 21a of the second portion 20 until the free end portionengages the unwrapped second one of the multiples 21a. This unwrappingof each of. the remaining four multiples 21a followed by the wrapping ofthe adjacent one of the multiples 11a vacated by the 'unwrapped multiplewith the free end portion of the wrapped multiple engaged and locked tothe unwrapped multiple is performed in turn, but with the four remainingcomplemental locked wrapped and unwrapped multipleslllaf andlZla spacedthe' same length' from each lother 'or in this instance 3 feet. Figure9A shows a portion Vof the spliced cable after the aforesaid Wrappingandunwrapping of the respective pairsv of multiples 11a and 21a havebeen concluded, the fifth and sixth pairs with thei-rterminating pointsE and F being only shown.
